Addition and subtraction word problems — Maths Olympiad practice

Olympiad word problems often need two steps, and the wrong options are the answers you get by adding when you should take away. Read the story twice, decide what happens to the numbers, then calculate.

How to solve it

Read twice, then choose — “the words tell you whether to add or take away”

  1. “More”, “in all”, “altogether” → add.
  2. “Left”, “get off”, “how many more”, “difference” → take away.
  3. Two things happen? Do them one at a time, in order.
  4. Asked for “at first”? Undo what happened: put back what was given away.

Use it for: Story sums in Class 2–4 Olympiad papers, and every school test.

Worked example: A school has 245 boys and 218 girls. 136 children go on a trip. How many children stay at school? → 327

  1. All the children: 245 + 218 = 463.
  2. 136 go on the trip, so take them away: 463 − 136 = 327.

Check: 327 + 136 = 463 and 463 − 218 = 245 ✓
